Chip-E Snow Rider

This chip-e is remixed by Pratyaksh Asarsa. I have given this a new ability to ski on the snow.I have tried to keep it as simple as I can.The concept is that two external servos are added on the both sides of the Chip-E robot.the servo horns are attatched to 3d printed rows. Skies are also added to the base feet for the smooth functioning of the robot.Please comment how I can add more abilities to the robot.
